Patented Mar. 2, 1937 PATENT OFFKIE WINDOW REGULATOR Albert W. Susor, Toledo, Ohio Application June 20,

4 Claims.

This application relates to regulators for windoWs and discloses a regulator of the ventilating type in which is incorporated an improvement in construction.

The object of the invention is to provide a construction for a ventilating cam which will permit the saving of an appreciable amount of metal as against the construction heretofore known.

For an understanding of the regulator, reference may be had to the appended drawings. In these drawings,

Fig. 1 shows the regulator in elevation;

Figs. 2 and 3 are sections on lines 22 and 15 3--3 of Figure 1;

Fig. 4 is a perspective of a regulator arm.

The regulator herein disclosed comprises a mounting plate H) on which is journalled a pinion ll adapted to be rotated by ahandle l2 and meshing with a gear M to which is fixed a regulator arm l5 having on its free end a pin l6 disposed in a slotted channel secured to the lower edge of a window I8 to be moved by the regulator. The gear l4 meshes with a second 25 gear IQ of equal size to which is fixed a second arm 20 having on its free end a pin 2| also disposed in the slotted channel on the lower edge of the window H3.

The arm 20 has a slot 26, having a central curved portion terminating at one end in a straight portion 27 and at the other end in a spread out portion 28. The arm is formed so that it has portions of its front surface lying in three different planes. The highest portion 32, that carrying the slot 26, is separated from the lowest portion by a curved bend 22. The lowest portion, 33, lies adjacent the gear l9 and is riveted thereto by rivets 23 and by the stud 24 which journals in the mounting plate It]. The intermediate portion 34, which is a connecting strip, is spaced away from the upper portion, to provide passage for pin 29 as explained later, and is also spaced away from the lower portion so as to be able to pass by the gear guard 25, which is provided to keep the gears in mesh.

The-operation of the regulator is as follows:

Assume the parts to be in the position of Figure 1. Under such circumstances the terminal portion 21 of the slot 26 will receive a pin 29 secured to the channel I! at the lower edge of the window. Initial rotation of the handle I2 in a counterclockwise direction will spread pins 2| and I6 and will cause horizontal movement of pin 29 without causing any appreciable 1936, Serial No. 86,267

vertical movement of pins 2| and I6, and will thus cause horizontal motion of the window l8 Without any appreciable vertical motion thereof. Further rotation of the handle |2 will cause vertical motion of the pins l6 and 2| and will bring pin 29 into the central arcuate portion of slot 26 which is so shaped that it causes return horizontal motion of pin 29 and Window l8 to their original forward position.

Continued rotation of the handle will cause continued vertical motion of the window until pin 29 reaches the end 28 of the slot 26 Whereupon due to the out of plane characteristic of the parts at such end, the pin 29 will leave the slot so that further movement of the handle will cause further vertical motion of the window without any horizontal motion of the window, until full open position is reached.

On reverse rotation of the handle, from this point, the window will be raised to some extent with no horizontal motion until the mouth 28 of the slot 26 reaches the pin 29, whereupon such pin will enter the slot, so that further movement of the window will be influenced by the engagement of the pin 29 with the slot 28. Continued movement of the handle will cause the window to rise with a rearward horizontal motion, until ventilating position is reached, whereupon continued rotation of the handle will cause forward horizontal motion of the window with no appreciable vertical motion of the same.

Heretofore it has been necessary to have slot 26 continue for another 20 to 30 degrees of its curved path in order to permit corner 36 to pass over gear guard 25 so that pin 29 might pass out of the mouth 28 of the slot. Such longer slot necessitated a greater low portion 33, such as shown in dashed lines at 33a in Figure 1.

The present construction, however, by stepping up the bridge 34, saves a considerable amount of Weight and of expense of material.

No-w having described a regulator of the invention reference should be had to the claims which follow for a determination of the monopoly sought to be covered herein.

I claim:

1. In a regulator of the ventilating type comprising two arms, each mounted to rotate and each having a free end slidably interlocked to an edge of a window whereby rotation of the arms in opposite directions will raise or lower the window, one of the arms having, in an ofiset portion, a slot arranged to receive a pin secured to the window, the slot being so shaped that rotation of the arm from one terminal position will cause the slot edges to move the pin horizontally, then move the pin in a reverse horizontal direction, and then permit the pin to leave the slot, a bridge or strip at the end of the slot connecting the edges of the slot and ofiset so as to pass by a part in the plane of one portion of the arm and at the same time to permit the aforementioned pin secured to the window to pass out of the end of the slot.

2. In a regulator having two arms mounted to rotate and having the free ends of said arms slidably interlocked to an edge of a window so that rotation of the arms lowers or raises the window, a slot in one of the arms in a portion thereof considerably out of plane with the hub portion of the arm, these portions being separated by a bend, a third portion connecting the first two at the end of the slot and lying in a plane between the first mentioned portions so that said third portion may pass, without striking, parts in the plane of aforesaid hub portion and so that said third portion may also pass by without striking a pin secured to the window and arranged to be received in the slot.

3. In a regulator adapted to raise and lower a window by the rotation of a pair of fixed center arms, an arm of said pair comprising portions in three planes, the first portion being the hub portion, lying at the center of rotation, the second portion being the outer portion and having a slot adapted to receive a pin secured to the window for the purpose of causing horizontal movement of the window, and the third portion being a strip connecting the first two portions at the end of the slot and lying in a plane between said first two portions.

4. In a regulator adapted to raise and lower a window by the rotation of a pair of fixed center arms, an arm of said pair comprising portions in three planes, the first portion being the hub portion, lying at the center of rotation, the second portion being the outer portion and having a slot adapted to receive a pin secured to the window for the purpose of causing horizontal movement of the window, and the third portion being a strip connecting the first two portions at the end of the slot and lying in a plane between said first two portions, the purpose of such interplanar situation of said third portion being to permit, on one side, passage of parts in the plane of the first, or hub, portion, and, on the other side, passage of the aforementioned pin secured to the window.
